Review on Tenergy 7.2V 2000mAh Replacement Battery for iRobot Braava 380 380t 390 390t & Mint 5200 5200B 5200C – Enhanced Power and Durability! by Ann Perez

The OEM battery that came with the Braava Jet lasted me almost 2 years (with very little use). When I replaced it with one of these, it only lasted a year, but the price savings more than made up for the limited lifespan. This battery costs up to 4 times less than an OEM (Original Equipment Manufacturer). Great purchase and I will use the same again if my car lasts long enough.
